Product details
Overview
TC1793F512F270EFABKXUMA2 from Infineon Technologies is a 32-bit TriCore V1.6 super-scalar microcontroller with 270 MHz CPU clock, 4 MB program flash (ECC-protected), 192 KB data flash for EEPROM emulation, and integrated PCP2 peripheral control processor operating at 200 MHz. It targets automotive powertrain and chassis control systems requiring real-time deterministic execution, functional safety compliance (ASIL-D capable), and high-integrity memory architecture.
For engineers reviewing the TC1793F512F270EFABKXUMA2 datasheet, TC1793F512F270EFABKXUMA2 pinout, TC1793F512F270EFABKXUMA2 application, or TC1793F512F270EFABKXUMA2 equivalent, key selection criteria include ASIL-D support via Safe DMA, dual-core real-time scheduling (CPU + PCP2), 64-bit crossbar interconnect bandwidth, and ERAY/MLI/SSC interface timing for distributed vehicle networks.
Technical Context
The TC1793 implements a dual-processor architecture: a 270 MHz TriCore V1.6 CPU with 6-stage pipeline, FPU, and MAC unit delivering 2 MAC/cycle; and a dedicated 200 MHz PCP2 coprocessor with 16 KB PRAM and 32 KB CMEM for offloading time-critical peripheral control. Both execute independently under shared memory coherency managed by the 64-bit crossbar.
Its safety architecture includes 8-channel Safe DMA (SDMA) with lockstep monitoring, dual-lockstep CPU mode support, ECC on PFLASH and DSPR, and hardware-assisted interrupt arbitration across 2 × 255 priority levels-enabling ISO 26262 ASIL-D decomposition in certified automotive software stacks.

Pinout & Package
TC1793F512F270EFABKXUMA2 is housed in a 296-pin LQFP package (24 mm × 24 mm, 0.5 mm pitch) with exposed thermal pad. Pin assignment follows Infineon's standardized TC1793 pin configuration (Document V1.2, Section 3.1), supporting dual-voltage I/O (1.3 V core / 3.3 V I/O), differential ERAY transceivers, and dedicated JTAG/DAP debug interfaces.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDDP_1.3 | Core Power Supply | 1.3 V supply for CPU/PCP2 logic; requires low-noise regulation and local decoupling for timing integrity. |
| VDDIO_3.3 | I/O Power Supply | 3.3 V supply for all digital I/O banks; supports mixed-voltage interfacing with external sensors and actuators. |
| ERAY_TXP/N | Differential ERAY Transmitter | LVDS-compliant output pair for FlexRay bus communication; requires 100 Ω termination and controlled impedance routing. |

| JTAG_TCK/TMS/TDI/TDO | IEEE 1149.1 Debug Interface | Standard boundary-scan and debug access; supports real-time trace via DAP interface with minimal pin overhead. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Processor Real-Time Execution | CPU + PCP2 operate concurrently with shared memory coherency-eliminates polling overhead for ASC/SSC register management in motor control loops. |
| ASIL-D Capable Safety Architecture | Safe DMA channels, ECC on critical memories, and lockstep CPU mode enable certified fault detection and containment per ISO 26262. |
| 64-Bit Crossbar Interconnect | Enables concurrent CPU flash access, PCP2 memory access, and DMA transfers without bus contention-guarantees worst-case memory latency ≤ 8 cycles. |
| Time-Triggered Communication Support | Integrated ERAY_PLL and MSC interfaces provide hardware-synchronized timestamping and schedule enforcement for FlexRay and proprietary time-triggered buses. |
| EEPROM Emulation via DFLASH | 192 KB on-chip DFLASH with wear leveling and atomic write support replaces external EEPROM-reduces BOM count and improves startup reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive real-time microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TC275T64F200NACXTMA1 | TriCore V1.6.2 core, 200 MHz CPU, 4 MB PFLASH, no PCP2 but enhanced GTM timer subsystem | Better suited for complex PWM generation (e.g., inverter control), less optimal for legacy ASC/SSC peripheral offload | Select when GTM-based motor control dominates over legacy ASC/SSC protocol handling |
| SPC574SADPT260S | Power Architecture e200z4 core, 180 MHz, 2 MB Flash, integrated ADC with post-processing unit, no ERAY | Optimized for body electronics and battery management; lacks FlexRay/ERAY PHY and PCP2 offload capability | Select for cost-sensitive ASIL-B applications without time-triggered networking requirements |
Compared with TC275T64F200NACXTMA1 and SPC574SADPT260S, TC1793F512F270EFABKXUMA2 uniquely combines PCP2 offload for legacy ASC/SSC peripherals, ERAY PHY integration, and 270 MHz CPU performance-making it irreplaceable in legacy FlexRay gateway and high-jitter-tolerance powertrain ECUs.

FAQ
What is the maximum operating temperature range for TC1793F512F270EFABKXUMA2?
The TC1793F512F270EFABKXUMA2 is rated for operation from −40 °C to +125 °C ambient temperature, validated per AEC-Q100 Grade 1 qualification. All electrical parameters-including 270 MHz CPU clock, PLL stability, and flash read/write endurance-are guaranteed across this full range with appropriate thermal design and voltage regulation.
Does TC1793F512F270EFABKXUMA2 support ISO 26262 ASIL-D certification out of the box?
No MCU is "certified out of the box," but TC1793F512F270EFABKXUMA2 provides all hardware safety mechanisms required for ASIL-D decomposition: Safe DMA, lockstep CPU mode, ECC on PFLASH/DSPR, and dual 255-level interrupt arbiters. Certification depends on software implementation, toolchain qualification, and system-level integration per ISO 26262 Part 6.
Can TC1793F512F270EFABKXUMA2 replace TC1767 in existing designs?
Direct replacement is not feasible due to pinout incompatibility (TC1767 uses 144-pin LQFP vs. TC1793's 296-pin LQFP) and architectural differences: TC1793 adds PCP2, ERAY, and expanded memory. Migration requires PCB redesign, BSP adaptation, and validation of new safety features-though functional overlap exists in ASC/SSC usage.
What debug interfaces does TC1793F512F270EFABKXUMA2 support?
TC1793F512F270EFABKXUMA2 supports IEEE 1149.1 JTAG for boundary scan and basic debug, plus Infineon's DAP (Debug Access Port) interface for real-time trace, memory access, and CPU/PCP2 core control. DAP operates over SWD or cJTAG and enables non-intrusive instruction tracing without halting execution.
